How to Write a Sentence Simple Sentence (noun + verb + modifiers) Compound Sentence (noun + verb + modifiers, and noun + verb + modifiers) Complex Sentence (If noun + verb + modifiers, noun + verb + modifiers) Whenever you write a sentence, concentrate on the subject (a noun) of the idea.  In other words, what are you writing about?  Then select the action of the subject (a verb).  I other words what are you going to say about the subject? Example: I am writing about “beauty.” I start with my subject:                   Beauty Next I think about what I want to say about beauty.                                  can be found So now I have a noun + verb structure. Finally, I complete the idea.  I am simply adding modifiers.                                                                only in the right places I now have a complete sentence:                               Beauty can be found only in the right places. I turn my simple sentences into compound sentences when I combine them with a coordinating conjunction (and, but, or)—don’t forget the comma. I turn my simple sentences into complex sentences when I combine them with a subordinating conjunction (when, because, if, although, etc.).
